IMPROVEMENT IN PRESSES FOR PACKING PUTTV.

Specification forming part of Letters Patent No. 166,066, dated July 27,1875 application filed March 4, 1875.

To all whom it may concern Be it known that I, LEON BOUGHER, of St.Louis, in the county of St. Louis and State of Missouri, have inventedan Improved Press for Packing Putt-y, of which the following is aspecification This invention is a press for packing putty in bladders.The ordinary way of accomplishing this purpose is by hand labor, the

operator taking the putty with one hand, and

stuffing it in the bladder held by the other hand until it is filled.This well-known way achieves but an incompact stuffing or imperfectfilling of the bladder; also, the bladder is frequently split; the mouthof it is difificult to tie; the oil is not sufficiently retained withthe putty; the freshness and quality of the putty are not preserved, andotherwise there is incurred loss of time, labor, and extra expense.

To obviate all this, my invention consists in the making of a machinefor packing putty, and to possess the constructive features andoperation, as will now more fully appear.

0f the drawing, Figure l is a front elevation. Fig. 2 is a sideelevation. Fig. 3 is a top plan.

A is the upright frame to support the mounted parts. B is the cylinder.The cylinder l form flanged at top, while at bottom it is coneshaped,terminating with a tube, 1), as shown in Figs. 1 and 2. The putty can bereadily entered top of the cylinder, and more uniformly forced out ofthe tube 12. The cylinder thus made is properly secured to the frame A,in connection with the parts that constitute the press proper. (J is arackbar. This I arrange to slide up and down in guide-bearings c 0 (Seefigures.) The lower end of the rack-bar carries the plunger 0 (See Fig.1.)

In order to impart the required reciprocatin g movement to the rack-bar,this is operated by the following gearing: D is the powershaft. Thisturns in proper journal-bearings secured to the frame A. At one end ofthe power-shaft is a pinion, d. This meshes with a gear-wheel, E. 'Thegear E is on a small shaft, 6, which turns in raised part of thebearings e 0 (see Figs. 1 and 3;) also, on the shaft e is the pinion ethat meshes with the rack-bar. To change the gearing operation withpower source, this I do as follows: I provide the power-shaft with thelarge pulley-wheel F and small pulley F, both of which operate looselyon said shaft. Fitted to engage either of the pulleys F F is a clutch,f, which the operator can slide by hand-lever along the power-shaft toengage in either of said pulleys. A'projection, f, on the shaft (seeFig. '1) secures the clutch firmly, so as to turn the shaft. When,therefore, the clutch f is fastened with the pulley F,'by means of thegearing-connection with rack-bar O, the same is operated to descend; andwhen said clutch is changed to gear with the pulley F, the said rack-baris raised.

The operation of my press is as follows: The rack'bar being in raisedposition, the cylinder is filled with the putty. The mouth of thebladder is held to the tube of the cylinder preparatory to filling saidbladder. The clutch device being brought into engagement with the pulleyF, the rack-bar descends. In doing so, by its plunger, it forces theputty to pass out of cylinder, filling the bladder. When the bladder isfilled the change of gearing takes place, which permits the expansiveforce of the putty to become sufficiently relieved from pressure, so asto prevent the putty from running out of the cylinder when the filledbladder is removed to be tied or closed. The next bladder being placedto the mouth of the cylinder, it is'filled in the same way. v

As is apparent, the packing of the putty is thus done in a most readyand perfect manner. Thebladder, being completely filled, can thereforebe more readily tied; also, the putty is rendered better for use, as theoil is retained, the quality of the putty preserved, and the packing iscompact.

What I claim is-- r l. The rack-bar 0, its plunger 0 the pinion. cgear-wheel E, pinion d, power-shaft l), in combination with a cylinder,B, to operate as and for the purpose set forth.

2. The clutchf, pulleys F F, power-shaft D, pinion d, gear-Wheel E,pinion e rack-bar (J, its plunger 0 in combination with the cyilnder B,to operate as and for the purpose set forth.

In testimony of said invention I have hereunto set my hand.
